METALLIC. RAILWAY-TIE AND FASTENING.

Specification of Letters Patent. Pate ted l y 9 191 Application filed March 17,1916. Serial na'ss'ssz.

1 '0' all whomit may concern:

Be it known that I, LAURENCE H. KIRK,

' citizen of the United States, residing at .Iavre (le Grace, in the county of Harford" and State of Mar 'land,have invented oer-y '"taiii"neiv and useful Improvementsin Metallic' R-ailway-Ties and Fastenings, of

t which the following is 'a specification."

My" i1ii'ention relatesi; to'an' improved "rneans 'for' fastening one part to another," "prirnarily the intention relates to'a rnetal-' lie railway tie and rail fastening and the tie formed "ofa singlepiece of'metal having "ceiying reccssesyor core-holes, yl1ieh at op-' posite ends have their walls stra ght and on the upper surface near the 'ends,;suitable seats for the rails, said tiebeing, also,

with a pair of .yertically disposed spike-re;

- 'f j' thence are {connected by }an L intermediate portion Whose alls are given a spiral for- I matio'n, said recesses or core holes being del signed for the reception of the spikes which Secure the rails to the tie or other part.

Myj invention further consists of the -pa rts,j 'and the constructions, arrangements and conibinatlons of partsjwh ch Iwlll '50 hereinafter describe andjclaim. I

; In" the I accompanying drawing forming fpartof this specification and in which similar reference characters indicate like parts in the several views; Figure 1 is aperspective yiew of a railway tie-as one einbodine nt of my invention, showingsect ons of the 'ra ls thereon, Fig. 2 1s anenlarged" a longitudinal sectional view on the'lin'e22 of Fig. 1, showing a spike secured'in' posi 40 7 tion.

While the present invention rriay'be' used Wherever it is' desired to securely fasten onepart to ianotherbyr means of a spike, or

I bolt, I have, for,presenti purposespillus trated'the present improvement in connection with a'metallic railway tie and fastening, which is not essentially unlike the tie disclosed in Patent No. 1,115,167, dated ()0- tober 27, 1914, and whichwtie consists ofa base flange, .21, of suitable width and a flange. 5, vwhich when the tie is imposition,

1 extends perpendicularly to the base flange and rises front the center thereof and extends from end to end of the base flange,-

said perpendicular flange being, for the sake oflightness and" amhe 'Samwme strength tendfol-a su table distance along the sides of the vertical flange'and thus form" broad and substantial seats for the base flanges of the 'usual rail i'ay a'i1 ,;13, seatshaving at the outer side's theiipstandingfshoulders,

7, formed rigid with the "reaical flang'e and against WhlC-ll" shoulders abut the outere'dges e, horizontal base' flangesfof"therails,

formedbelow the sides of each rail seat;

the vertical flange ot the tie beneath said seats may be forrne "#withop eniiigs,"h, but

this is optional. I f .Y V w f t? 'lhe foregoing features form'noessentlal part of my present in enti'on and hence I do not broadly claim the sa1ne, as it is apparent that the improfei'nent whichII am about codeseribema be used with other and different forms tr ranwa ties and as a fastening means, not only between a tie and a rail, but between 'any' two parts which it is desired'to rigidlysecureoneit0 the other, by means of a spikejorbolt. V

In the aforesaid priorfpatent, suitable vertical boxes .are located "atjoppo'site sides of and verticallybeloiy each rai1 seat,eaeh of said boxes forming "a, spike receiv ing recess longitudinally of serpentineform, in which the ordinary and substantiallyjstraight rail- Way spike isv.i designed ,tofbe fdriven' and to bedistoited during driving operation, whereby the spike is made to substantially conform longitudinally the'l Wavy outline of the walls of the recess against which the- 100 spike is forced'as it is driven iritoplace. In the presentinstanee, however,, it is desired to give to the spike, or to an equivalent bolt, a SPiraLtWi'st'rath'er than a longitudinal Wavyform and "to'thisend, I form 105 the spike receiving recesses or core-holes as follows: At each endfof therecess or corehole, the Walls of thesarne are parallel and straight, as at 22, for a substantial distance inward, the recess "or opening being, 1 0
